CNC Turned Milled Wheelchair Parts Aluminum Stainless Steel Nylon
High Precision
Common Wheelchair Components and Their Processing Technology
1. Turning
Turning is mainly used for machining rotationally symmetric parts,
suitable for cylindrical or disc-shaped parts.
Common Applications:
Wheel Axles: Wheelchairs typically require high-precision turning
to ensure compatibility with the wheel hub and bearings.
Bearing Seat: precision turning to ensure the installation accuracy
and durability of the bearing.
Foot Pedal Shaft: Turning is used to manufacture the rotating shaft
of the foot pedal.
Connecting Rod: Some cylindrical connecting rods require turning
processing.
2. Milling
Milling is used for machining flat, groove, hole, and complex
shaped components, suitable for non rotationally symmetric parts.
Common Applications:
Frame Connectors: Wheelchair frame connectors typically require CNC
milling to ensure installation accuracy and strength.
Seat Bracket: The complex shape and installation holes require
milling processing.
Brake Components: such as brake levers and calipers, typically
require milling to achieve complex shapes and high precision.
3. Drilling
Drilling is used to process installation holes or connection holes
on components.
Common Applications:
Frame Hole Position: The installation holes on the wheelchair frame
need to be drilled.
Seat Adjustment Hole: a hole used to adjust the position of the
seat.
Armrest Installation Hole: The fixed hole position of the armrest.
4. Boring
Boring is used to machine high-precision inner holes, usually for
the installation of bearings or shafts.
Common Applications:
Inner Hole of Wheel Hub: Ensure precise matching between the wheel
axle and the wheel hub.
Bearing Installation Holes: High precision bearing seats require
boring machining.
5. Grinding
Grinding is used for high-precision and high-quality surface
machining of components.
Common Applications:
Wheel Axle Surface: Improve the surface smoothness and accuracy of
the wheel axle through grinding.
Brake Disc: Grinding is used to ensure the flatness and braking
effect of the brake disc.
Metal Used for CNC Components in Wheelchairs
| Metal Material | Common Grades | Characteristics | Typical Applications | Selection Factors |
|---|
| Aluminum Alloy | 6061, 7075 | Lightweight, moderate strength, good corrosion resistance, easy to
machine | Frame connectors, hubs, armrest bases, footrest brackets | Lightweight, cost-effective, corrosion resistance |
| Stainless Steel | 304, 316 | High strength, excellent corrosion resistance, heavier | Axles, brake components, seat frames | High strength, corrosion resistance, heavier |
| Titanium Alloy | Ti-6Al-4V | Ultra-high strength, lightweight, excellent corrosion resistance,
high cost | High-end frames, axles, competition-grade parts | Ultra-high strength, lightweight, high cost |
| Carbon Steel | Q235, 45# Steel | High strength, low cost, heavier, prone to rust | Low-end frames, structural components | Low cost, heavier, requires surface treatment |
